BALL-BEARING HUB.

SPECIFICATION forming part of Letters Ilatent No. 679,995, dated August 6, 1901. Application filed February 26, A1901. Serial Nol 48,934. (No model.)

To all whom; it may concern.-

Beit known that I, PHILIP F. SCHAFFER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Ball-Bearing Hubs, of which the following is a specification, reference being had therein to the ac companying drawings.

This invention relates to ball-bearing h ubs, and particularly to means for applying such bearing to the axle and hub of a Wheel.

The invention has for an object to provide novel means for securing a bearing-sleeve against rotation upon the Vaxle and for also holding a bearing-cone in position while permitting adjustment of the several parts to compensate for wear and permit their removal when desired.

Other and further objects and advantages of the invention will be set forth in the following description and the novel features thereof dened by the appended claims.

In the drawings, Figure l is alongitudinal section showing the invention applied to an axle; Fig. 2, a vertical section on the line 2 2 of Fig. 1; Fig. 3, a similar view on the line 3 3 of Fig. l. Fig. et is a detail perspective with parts broken away,showing the manner of securing the bearing-cone against rotation. Fig. 5 is a longitudinal section of a modified application of the invention, in which one set of balls is used-at each end of the hub. Fig. 6 is adetail perspective of the lock-nut for the bearing-sleeve, and Fig 7 is a similar view of the lock-washer. y

Like letters of reference refer fto .lil'iepa'rts in the several features of the drawings. y,

The axle A, to which the bearing is to heap# plied,is provided at its end with the threaded portion A', having therein a longitudinal slot A?. y

The casing B is formed o f a front boxing B an'd a rear Abox B2, which may be joined together in any desired manner -forinstance, by threading B3. The rear box is provided with securing-pins B4, adapted to retain the same within a wooden hub by entering the material thereof. Each of these boxes is provided with a groove or way B5, extending inward from the open end of the box and through the threads B6 thereon. At each. end of the casing a bearing-sleeve Gis secured to and fitted upon the axle A and provided at its outer end with a series of sockets or wrench-holes C. For the purpose of locking the front sleeve in position a washer Dis provided, which is adapted to slip over the threaded portion A and has a lug D' passing into the slot A2 to prevent rotation of the Washer. The face ot' this washer is provided with a lock-pin D2, adapted to enter the sleeve, and thus hold the same against rotation, while the washer D is firmly held in position `by means of a lock-nut D3 engaging the threaded portion A of the axle. At the rear end of the casing a washer E is tightly fitted to the axle and may be provided with a pin E' to enter a socket in the shoulder of the axle to hold the washer against rotation. A lock-pin E2 upon the opposite face of this washer is adapted to enter the socket C" in the bearing-sleeve, and thus hold the latter against rotation after it has been adjusted to the proper position.

Asectional bearing-coneF may be provided for each of the boxes and is formed with 1u bricating-apertures F' opposite the raceways F2, within which the balls Gr travel. The outer cone-section is provided at one face with a threaded portion F3, adapted to engage the threads BG of the boxes,and with wrench-holes F4. The secured or middle cone-section F5 is provided with a lug F6, adapted to travel in the groove Bof the case. The rear cone-section F7 iits against the shoulder of the casing pendent of each other, `so, that in assembling the bearing the back and middle sections are slipped into position and the adjustment secured by the front threaded section, while the lug upon the secured section causes the same to be positively rotated with the hub and casing.

, At the outer end of the front bearing-box B a dust-cap H is applied and provided with a threaded periphery H to engage the inner face of the casing. In order to prevent this cap from moving the adj usting-cone when being screwed on, an annular loclvplate I is placed over the face of the adj usting-cone and provided with a lug I', entering the slot i'n the box, by which the plate is held against rotation. (See Fig. 7.) l

The rear boxing isprovided with a suitable packing J, between the ad justin g-cone for the sleeve and the dust-guard J', threaded into the open end of the boxing B2. Betweenthis dust-guard and the adjusting-cone a lockplate L, having a lug L', entering the groove of the box, is located to prevent movement of the cone when adjusting the guard.

In the modified application of the invention shown in Fig. 5 all ofthe parts are similar in Construction, arrangement, and operation to that shown in Fig. 1, with the exception that one section of the bearing-cone is omitted and atA the left end the groove A2 is extended beneath the sleeve O, which is provided with a projection C2, entering said groove, thus holding the sleeve against rotation without the use of the Washer D. y

From the foregoingdescription the operation of the several parts will be clearly understood, and it will be seen that the casing can be readily applied to a hub and the bearing members adjusted and secured by an ordinaryworkman. Furthermore, the construction of `the lock-washer for holding the Abearing-sleeve permits the convenient removal of the sleeve for any purpose desired, while the positive connection between the rotating case and one section of. the bearing-cone always insures a proper movement of the balls,which prevents a disarrangement of the bearing-contact therewith, thus securing the most desirable freedom of action between the several parts. The plates between the adjustingcones and the dust guard and cap also pre- Avents any danger of a movement of the cones if either the guard or cap be removed for the purpose of lubricating the hearing or cleaning the same.

It will be obvious that changes may be made in the details of the construction and configuration of the several parts Without departing from the spirit of the invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by 4Letters Patent, is-V I. In a ball-bearing for hubs, a bearingsleeve adapted to slide upon an axle and engaged therewith against rotation, a casing having a longitudinal groove or way, a bearing-cone adapted to slide into said casing and groove or way, a bearing-cone having a projection entering said groove, balls between said sleeve and cone, an adjusting-cone cooperating with said secured cone, and a lockwasher for said sleeve havinga projection to engage the axle and a pinto entersaid sleeve; substantially as specilied.

v'3.'.In a ball-bearing for hubs, an axle provided with a slot at one end, a bearing-sleeve having a socket therein and adapted to be secured to said axle, a casing having a longitudinal groove or way, a bearing-cone having a'projection entering said groove, balls between said sleeve and cone, an adjustingcone cooperating with said secured cone, a lock-washer for said sleeve having a projection to engage the axle and a pinto enter said sleeve, a closure for the end of the bearingkbox, and a lock-plate between said closure and `the adjusting-cone and havinga lug to enter the groove ot' said casing; substantially ,as specified.

4;.' In a ball-bearing hub, the combination with an axle having a longitudinal groove in its outer end, of an nnthreaded bearing-sleeve adapted to slideupon said axle and provided with a socket at one end,a lock-washer having a lugto enter the groove in said axle and a pin Vto enter a socket in the end of said l sleeve, a threaded nut adapted to engagethe end of the axle to hold said lock-washer in position, and a casing surrounding said sleeve provided with bearing-balls; substantially as specified cones threaded into said boxes, bearingsleeves adapted to tit the axle and provided with a socket at one end, lock-washers having a pin to enter said sleeves and a lug to enter a groove in an axle, a dust-cap threaded upon the outer box, a plate between said cap and adj usting-cone, a dust-guard threaded upon the inner box, a plate between said guard and the adjacent cone having a lug to hold the plate against rotation, and bearingballs between -said sleeves and cones; substantially as specied.

In testimony whereof I alflx my signature in presence of two witnesses.
